Think about other asian restaurants in Chinatown as a functional iPhone 6 priced at $300, then Orange Rouge is a iPhone 7 priced at $600+: most likely you don't notice the difference, but the little extra could be worth the price depending on what kind of consumers you are.
I would have given you an objective 4 star for the food (on the salty side but creatively spiced and well presented), but i will instead give it a 5 star because no other Asian restaurants in this city can provide such attentive service!
I do notice that I'm the only Asian person here, but I think most Asians come to Chinatown for inexpensive and traditional comfort food, but they don't provide any of that, hence the bad rating from some people. Just compare it with other trendy new cuisine such as Lawrence in Mile-end or fine cocktail bar such as Le Mal Neccessaire, then you won't think it's overpriced! All dishes are different - from soft shell crabs in fried rice to raw beef in extremely tasty Vietnamese spices; and despite the duck is twice the price as the one you get 20metres away in a traditional restaurant, it is so perfectly seasoned that you won't regret trying them.
